Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material ExtractionQuarry. The raw cement ingredients needed for cement production are limestone calcium, sand and clay silicon, aluminum, iron, shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
Manufacturing of cement involves various raw materials and processes. Each process is explained chemical reactions for manufacture of Portland Cement. Cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. When mixed with water becomes a hard and strong building material.
